This collection of twenty-nine research papers is dedicated to the eminent Balticist, Slavicist and Indo-Europeanist, William R. Schmalstieg in commemoration of his seventy-fifth birthday. It contains contributions by specialists of mainly Baltic and Indo-European linguistics which are reflective of Schmalstieg's own scholarly interests over the decades of his career, including technical aspects of Baltic and Indo-European phonology, morphology and syntax, etymology, language universals, the history of linguistics and the Baltic text tradition. Contributors include prominent scholars from the United States and Europe, both east and west. All papers are in English, and all linguistic material in less commonly known languages is provided with an English translation, making the contents accessible to a wider audience of readers.
